Diagnosing Sluggish Performance

If Investor/RT seems to be running sluggishly, it may be because a particular indicator in some chart is taking an excessive amount of time to calculate. Follow these steps to diagnose further:

Volume Profiling non-Time Based Charts

When applying start and stop times or a specific number of minutes to the Profile Indicator, Investor/RT is using the begin and end times of the bars in the chart to determine when to begin and end the Profile Indicator. On a Time based chart this is easy since each bar tends to start and stop at an even minute interval.

However, when adding a Profile Indicator to a non-time based chart (Volume, Tick, Range or Change bar charts), each bar does not have an even begin and end time and these times are not known until after a bar closes and a new one opens.

Range Bars and Change Bars in Version 12

Investor/RT Version 12 and higher adopts the convention that the size of the range or change of each bar be expressed as the number of tick increments of range or change. In Version 11, range/chart bar periodicity has been expressed differently, as the number of prices within the range bar, a number that is one greater than the number of tick increments in the range.
